Like a good financial portfolio, it appears that
diversification is a successful strategy for America's Energy Productivity
according to the environmental action group, Natural Resources Defense Council (NRDC). But, the NRDC notes that while the energy portfolio
clearly should include a combination of all energies, the single most effective
tool in maximizing our energy portfolio is to reduce consumption, extracting the
most out of every energy dollar spent.

The NRDC's report which was released on October 8, 2013
cites that because "the United States has found so many innovative ways to save
energy, the nation has more than doubled its economic productivity from oil,
natural gas, and electricity over the past 40 years." This translates to energy
efficiency contributing more to meet the nation’s needs than all other
resources combined.

Maximizing our energy efficiency is paying off. The energy efficiency
turnaround is documented by an NRDC analysis demonstrating energy use below
that of 1999 levels despite a 25 percent growth in the economy over the same
period. The NRDC reports that, "Factories and businesses are producing
substantially more products and value with less energy; the amount of gasoline
per mile driven is down; and the cost of all energy services (from lighting to
refrigeration) also has decreased." This makes the United States less dependent
upon foreign resources and more competitive.

Further good news is that in addition to saving billions of
dollars in savings, climate-warming carbon dioxide pollution is down, putting
the country on track to meet the Obama administration goal of reducing by 17%
over the next seven years.

The salient contributing energy savings highlights include a
package of serious reductions and efficiencies in each of the following categories:
electricity, oil, coal, natural gas, nuclear, renewable energy led by wind but
supported by solar as well.

Regulatory changes are also benefiting the bottom line by
providing energy efficiency standards and financial incentives. These changes are
also setting new fuel standards to reduce oil imports by more than 2 billion
barrels per day.

NRDC projects that on its present trajectory, energy
consumption will be cut by an additional 23 percent by 2020 saving nearly $700
billion that will be spent elsewhere. This will in turn, create an estimated
900,000 jobs. This will be accomplished by continuing to upgrade our real
estate and its infrastructure; continue to tighten efficiency standards for
buildings, equipment and vehicles; and rethink state regulations for
encouraging consumer energy savings programs.

So while necessary to consider all forms of energy use the
method that contributes the most to the bottom line is consumption reduction
and resource efficiency.
